Check groups

The group details page includes the fault list, alarm history, alarm rules, group resources, events, and group resource metric data.

Group list

The group list displays all the groups on the CloudMonitor. You can also view the resources and health condition of each group.

Parameters

Group name: The name of a group.

Health condition: The alarm status of any group resource. The group is healthy when add, modify, and no active alarms for any group resource. The group is said to be unhealthy when any of the resources has active alarms.

VM count: VM count is the total number of servers (ECS servers and other servers) in the group.

Resource count: The total number of resource types in the group. For example, if the group has ECS, ApsaraDB for RDS, and Server Load Balancer instances, then the total number of resource count is three.

Unhealthy Count: The total number of instances with active alarms in the group. For example, if two ECS instances and one ApsaraDB for RDS instance have active alarms, the number of unhealthy instances is three.

Creation time: The time when the group is created.

Actions: Four types of operations are supported namely copy this group and create a new group, enable all the alarm rules and disable all the alarm rules, and delete groups.

Fault list

The fault list shows the resources with active alarms in your group. This allows you to quickly view all the unhealthy instances and troubleshoot faults in time.

Note

When multiple metrics of a resource have active alarms all at the same time, the fault list displays the resource multiple times. Each row of the list shows one metric with an active alarm.

Once you disable the rule hit by active alarms, the resources and metrics associated with the rule disappears from the fault list.

Parameters

Faulty resource: A resource with an active alarm.

Start time: Time when the first alarm is generated.

Status: Displays a message indicating that a resource has an active alarm.

Duration: The time duration when a faulty resource is in the alarm state.

Alarm rule name: The name of the alarm rule applied to a faulty resource.

Actions: Click Expand to view the metric trends of a faulty resource with an active alarm for past six hours, and compare the metric data with the alarm threshold value.

Alarm history

Alarm history provides the account of all the alarm rules applied to a group.

Note

You can request for the alarm data history of the past three days. If the interval between the query start-time and end-time exceeds three days, the system prompts you to re-select the time range.

Parameters

Faulty resource: Resource with an active alarm.

Duration: The time during which a faulty resource is in the alarm state.

Occurrence time: The time when the alarm is generated.

Alarm rule name: The name of the alarm rule applied to a faulty resource.

Notification method: Method by which alarm notifications are sent. These notifications are sent through SMS, email, or TradeManager.

Product type: The product type where the faulty resource belongs to.

Status: The status of the alarm rule such as the alarm state, cleared state, and channel silence state.

Notification object: A group of contacts who receive alarm notifications.

Alarm rules

Alarm rules display the list of all the alarm rules applied to a group. You can select the preferred alarm rule from the list and can enable, disable, and/or modify the rules as per the requirement.

Note

The alarm rules list only displays the alarm rules applied to a specific group. It does not show the alarm rules with Resource Range set to the All Resources or an Instance.

Parameters

Policy name: Name of an alarm rule (policy) specified when the policy is created.

Status: Displays whether or not, the resources associated with the alarm rules have active alarms.

Normal state: All resources associated with the alarm rules are normal.

Alarm state: At least one instance associated with the alarm rule has an active alarm.

Insufficient data: At least one instance associated with the alarm rule has insufficient data and no instance has an active alarm.

Enable: Enables the alarm rule.

Product name: Name of the product which group resources belongs to.

Policy description: A brief description of alarm rules setting.

Actions: The optional operations include Modify, Enable, Disable, Delete, and Alarm History.

Modify: You can click Modify to make changes in the alarm rule.

Disable: Click Disable to disable the alarm rule. Once the alarm rule is disabled, the alarm service does not check whether metric data exceeds the threshold value.

Enable: Click Enable to enable the alarm rule. Once you enable a previously disabled alarm rule, the alarm service checks the metric data and determines whether to trigger an alarm based on the alarm rule.

Delete: Click Delete to delete the alarm rule.

Alarm History: Click to view the alarm history of the alarm rule.

Group resources

Display all the resources of a group and health condition of the resource.

Parameters

Instance name: Instance name or ID of a resource.

Health condition: The alarm status of any group resource. The resource is healthy if no alarm is generated according to the corresponding alarm policy. The resource is unhealthy if it has an active alarm.

Event

Currently, the alarm rule (policy) provides the alarm history and records alarm policy operation events (add, modify, and delete), allowing you to trace any operation performed on a specific alarm rule.

Metric chart

The lower section of the group details page displays the monitoring details of group resources. By default, CloudMonitor initializes frequently used metric data. If you want to display more metric data or change the chart type, modify the charts and customize metric data and/or the chart type.

Note

To obtain the OS metrics of ECS, you must install the CloudMonitor agent.

Initialized metric data

The following group data is initialized by default. If you want to view more metric data, click Add Metric Chart to add more metrics to the data.
